Abstract

The invention relates to a dehumidifying apparatus comprising an adsorbing element, having a plurality of groups of passages (2, 3) that are separated from each other and wherein heat can be conducted between each other said plurality of groups of passages, a moisture adsorbent (6, 7) on the inner surface of one group of the passages of said adsorbing element, in use in a dehumidifying process of gas to be treated, said gas to be treated flowing in one group (2) of the passages of said adsorbing element and at the same time a cooled gas to evaporate the water remaining in the other group (3) of passages flowing in the other group of passages, and in the process of desorbing said moisture adsorbent a high temperature reactivating fluid remains in the other group of the passages of said adsorbing element flowing. <IMAGE>
